To all whom it mrtylccncern:

Be it known that I, GEORGEW. Do'NNrNG, a

citizen of the United States, residing at Stamford, in the county of Fairfield and yState f Connecticut, have invented certain new and useful Im rovements in'T e-Writers; and I do heregy dciare thefcl owing-to be e full, clear, `and exact description of the invention, suchas will enable others skilled in the art to which it appertainstornaire and usepthesame. t y

.This invention relates to e-writers, and particularly to a' combination work-holder and rimitiearbon carrying and holding device.A Y

The ob'ect of my invention is to provide sim le, e eetive, and easiiyoperated devices sheets fromn for eeilltating 'and perfecting the c erationn of and greatly expediting the'wcrk' o the op- 'rator, in connection with devices' for holdrieig and lifting or se aratin'g a plurality 'ocerllion at"piaten or from the iv'ofi sheets sustained thereby and forclexnping the having operatmg mechanism b "il which they may be simultaneous y raised'for'" work-sheet to seid pieten, 'these various; parts for holding, separating, and clamping'YYY the Work being operatively connecteci''endYV means AofY permittin arrangement of 'theivoriroriof ered and eid down Ywhile the impression'is being made, nii ofv whichoporations ere ef.

With these objects in view i'. preferably areffecting the proper return of the various opraige the plurality of carbon-sheets on e perholder to engage and press upon the work-- iaten,'vvith ineens for Ykeeping the'. tape worV tholder tent when Vit is so raised A further object of my invention it to pro- A VVAnother ob}ect is toV provide automatic y' IDO menent fixture, such ,as a roll or e plurality .oi rolls mounted on the track-frame on the laten or on the table, and in connection therewith provide devires for fliolding, for raising, and for se arating the free edges of the respective car ori-sheets for fcciltating the rapid insertion and removal of the work sheet or sheets upon which the impression is made. placed beneath the upper sheet of carbon, es well es the work-sheet placed thereon, shall be firmly held to the platen while being written upon, I provide, in connection lwith seid earbon holding, raising, and sepeieting device, a work-holder clcmp or Aclemps operable by or independent of said device.

The invention resides also in various novel constructions and arrangement and combinetion of parts, as will be hereinafter more fully described and claimed.

In the accompanying drawings, forming u part of this specification, I have illustrated one of m'n' .embodimentsof my invention, it be erstood thetthe seme is susceptible o embodiment in various forms and yet be within the Spirit of my invention.

In the drawings, Figure 1 is n View in side elevation of a fiat-platen ty e-writer, the longitudinal trecks of which ve been, broken sway, showing the errengement of the eerbon-rolls, two carbon-holders, e work-confinin clamp, and the foot lever or .treadle for e eating the raisin of said carbon-holder and the work-conning clamp simlutnneously. Fi 2 is a View 1n plan thereof with the movabe .carriage oniitted. Fig. 3 is a. view similar' to Fi 1, with the movble cerriege and the trac therefor omitted, showing thecerbon-holders and the work-confining clamp in the positions which they assume, respectively, Wbn'the foot-lever is operated. Fig. 4 1s a 'New in front elevation, showing the position of the ports when elevated as shown in Fig. 3. Fig. 4 is. a transverse 'secF tion through the work-confining clamp and the carbon-holder levers, showing the rela.- tion of -tLese parts to each other and to the edge ofthe platen. Fi 5 is e view-in detail of the upper carbon-hol r and lifting device. is a similar View of the lower carbonF ho enand lifting device. Fig. 7 is e transverse sectional viewof the letter device, taken on the line 6 6, Fig. 6. Figs. Bend 9 are views in .detail in front and end .elevation of the work-confining clamp 4ernmi-g'eil et one side of the platen and orated simultaneously with the carbon and separating devices. Fig. 10 is a view in detail of e connectingieee for efiecting cooperation of the two eer on holding and separating devices and the work-coumin clamp. Fig. 1l is ny view in detail of the evice for effecting return of the o eral e parts to normal position. Figs. 12 a 13 are respectively views in 6 5 side elevation and in plan of e modified form As it is desirable that the work-sheet of the structure as organized for reflecting automatic raising of the carbon-holders and workholder.

Referring to the drawings, A designates a longitudinally-traveling carriage supported on a track-frame B, vmich is disposed indc- `pendent of or in position to rest upon e flut platen C.

D designates it transwrsely-inoveblc csrriege disposed on the longitudineily-movable carriagelA, already referred to.

The truek-freme and the platen nro preferably supported on a table' E, provided with su porting legs or standards e, nominated by s. moe e .et their lower portions and b e second brace e2 et their upper orton. rear end of the track-frame is provided with e stop or abutment B3 to limit the back' ward trnvel of the carriage A,

Arranged, preferably, to (be rw of the platen C and on the table E toward its rear edge ere brackets F F2, preferably secu red to. the table in any preferred manner, as by the screws f f/ Rotatebly supported on the y brackets F F2 are rolls G and H, res Wely, A which are designed to cart the car n'paper vin long continuous lengt is, preferably, and to be drawn therefrom and positioned over the platen and held et the from; by devices hereinafter more full. to be described. It is to be understood t t while I here only number may be emploved wit wut changing my invention. The roller Gis mount/rd on e shalt g, which rotates in bearings g wd carries adjustable sleeves g. From t 's roll G is preferably unwound the upper csrbonf ysheet G. The carbon may have trensverse or lo itudinal strips of colori different from t body or main portion of t carbon sheet, 4as shown in Fig. i3, 'Ilae'roll H is similarly munged. on e shaft fi, rotatebl supported in bearings It h .and carrying e 'usteble sleeves k. This roll Il cernes c lower carbon-Sheet H". The particular e011 struction and arrangement of these carbonrolls G and H constitute the subjectfmatter of another of my pendin applications, tiled February 14, 190.3, Seri No. 143,421, and will not, therefore, be claimed specifically herein. Also supported by a shaft i on the brackets F F is a. tape-tensioning roll I for holding the rear end of e workmnning m-pe I, more particularly described and claimed in mygindiig application tiled February SD, 1903, rial o. 142,788. The tape I is se, eurednt itsforwcrd end to e tapediolder I', which is more particularly described and claimed in iny ending application filed February 6, 1904, erial No. 192,403, and like the 'tapcfholder I is transverscdy movable over the laten C.

'l e carbon-sheet Grz is engaged at its for- Werd end by e cairbonclamp holderJ, which `may be of any appropriate wnstruction; beit shown two rolls of .carbon i1V l eater or less' 'LOC serrare@A in this instance I have shown the ssrne es comprising two superposed members j j, pivoted together at one end et j, so that the member y' may he swung outward from the ,member j to permit insertion of the end of the: carbon, it being understood .that the two members when in normal holding position are close together. Projecting upward frcrnthd outer end of the member i2 is a stud j, which, is received in the slotted end of nuernberg'.r The seid oarbon-holder J is pref erabl arranged on or secured to a bracket or stan ard is, and this is mounted, as h lscrews j", to enorm or lever J Fig. 5, whic x5 is provided at a point somewhat in advance A of its rear end with a perforation j, through l which posses a. spindle L, which is mounted transversely' beneath the platen in brackets l ZVand is providedwith e spiral spring l, engaging at one end with a collar l, keyed toY the spindle, and having its other end beer?n ing'egainst the under fece ofthe platen C, es shown in Figs. 2 end 11. It is to be undorV stood that s perforation y lsofthet thetleQver J is renf dered rigid with the spindle. Beyond the perforation j in thelevarsil is, another perforation j, whichis pgelretttel by.. s. screwor bolt mtoY connect seidV leves *Venite fulcruni tothe pindle L ts tightly within the" end is provided Yneit-lr eheh n?, which may carry an edgustin'gscrew n, b means ol' which, if desiredgos when but e, single carbon is employed, the lever N1 may be rigidi` Vsecured to spindleY 1L.n intermediate otthe 7o length of the iever N2, and preferably some Y distance removed from its point of seeure-- ment to the spring element L, is an elongated slot o?, and designed to work in'ths slot end also penetrate a. perforation j* in the 7 5 lever J is a connecting-bolt 0,'having on one o-its ends s, nut o, the bolt normally occupying the lower Vortion of the slot, as shown in Fig. 1; W en the foot-lever connecting with the lever Jz is o ereted to elevate the 8o forward end of said lever, said bolt 0 will ride in the slot tz'runtil norton thereof, when b werd movement of the ever it reaches the upper the continued u Y J* the Ileifer be caused to be raised atits forward end 8 5 iosition shown in lines inFig". 3f., It wi Y theY :irren emetthus described end"shn'fru thegieverzrwirill first he moved and hnverits forward engl 'elevated and dur-in the conrseAA 9o ''its ,u VnisrY'movement cause t e lmliftoV Linosa t ejever'N, and thus the 'eversnnj' hiegs'dedfns having both successive hnd'si-f sneossmoement.

To vguide themovement Vof theJever J* I provide thereon s. boss or projeetionrJ, esigned to hear against the sideof the platen and guide the lever Jinzts upward move ment and also prevent binding during such operation. Y Y Y Y The carbon-sheet His engaged at its forward end b/ s. carbon-olanxpholdcr N, which is recreb of construction imilar to the 5 5 cadlmn-holr er J, already described, compris- ,ing the two Vmembers n. n, ivoterl together at n.

The lever N is preferably arranged in juxtaposition to the lever .lnmlis pivotod ut its rmu und loosely on Vbrick to t re levers Vare elevated to iferent relative@ 5 hei hts away from the platen, and thus Vthe V'oer ori-sheets GH?, res eetiirelv1 will beelejj' voted to different hing ts' relative to eeeh,` other and to the platen, the carbon-sheet Gf being above Vthe carbon -sheet H2.

t will be'understood that the,olemtton'= and reisingofthelcerhomsheets G and EH to dierent reetively will eieet the 1 1o se ration "of YtheY work-sheets, between w 'ch said V#carbon -lshcets are interposed. The work-sheets may' the'n be withdrawn without `necessity ofthe operator touching the carbon-sheets, and their new Work-sheets rr 5 may be inserted, and" upon release of the ressure on the footelever device the carbon# rglder o @rating levers will he actuated laten b the spring-,actuated spindle L, en Y the wor -shcets 'wiil then be in r 2c positionVv che writtenupon. It wl be obected without necessity of `the operator util sing Vhet hands to operate the carbon-heiders; het, on the contra the Yogorxrtors r2 5 hands have heen free for t c proper removelf and irserton of the worksheet, and not havi ,g to handle or touch the carbon-sheets and toen the work-sheets it is manifest that there the spindle L, already described, and to this Wil he Vno 'srnntting of said worksheets by x30 be observed that'lgy @press both of om 'levers Jl and N', ma"

r'served that this'entire operation has been efs Y the fingers of the operator Besides, the handling of the work-sheets is thus greatly facilitated in removingand ,inserting them, permitting expeditious writing up of the said sheets and in a neat and cleanly manner.

It is to be understood that, if desired, I may employ in lieu of theQfoot-treadle a 'handdever properly disposed and connected with the carbon-holder-operating lever J2.

As a means for holding the work-sheet I may employ, in addition to the work-holding tape I, a clamping memberr P, preferably disposed at the edge of the platen C and in juxtaposition to the carbo'nwholder-operatf 1n levers Jz and N and of the form referab y shown in Fig. 9, comprising a p ate 77,' having its upper edge p2 bent over,sothat it may engage and hold the paper against the platen. his clamp P is preferably provided contiguous to its lower edgend by preference near its ends with inward-projecting studs or pins p, which are -designed to engage the lower face of the platenwlien the clamp, is raised (in the marinier resently to be described) and serve the dualp function of. limitingr 'thextent of upwardmovemen't of theclam and also for guidirgsuch movement oft eclamp-as,for instance, if the pin at one end strikes the lower faee'of the platen first it will hold .the clampatlthat end in a .raised position until the in at the op osite end engages the lower accjof the p aten, when the u per nturned edge of the clamp will, as iso vious, be properly arranged in a position above but level with, the upper face of the platen. I may, if desir'ed, elevate this clamp, so asto free it from engagement with the work-sheet and the' upper face of the platen in any desiredmannen; but I elect to operate it simultaneously with and by the same mechanism employed to elevate| the'ar-4 bonholders already i eseribed, and. tozfthis) end provide the clampl with); perhgrationlV p, preferably half-way of the-length of the, clamp, and through this perforation thelbolt penetrates, as shown in l"ig., 2, the saine. as it penetrates the lever J. 'lhis clamp Al is preferably extended baek ofthe pivotal point of the levers J and -Nz on the spindle L. 'l`o`j permit the raising ofthe clamp free of said spindle l1, provide the clamp with a eut` out or slot so that the samegwill bridge the spindle. t is to be understood that by reason of the connection by tht` bolt of the clamp I with the lever J* saidfelamp will be raised when the lever J is operated and the` pins 7: will guide and limit thi-upward movelnent of said i-.lamp in the manner already described. 'lhcre is thus a eoaetion between the carbon-lmelder-operating levers andth'e` said clamp, so that when the icarlion-sheets are elevated away from the Yplaten and eilect a separation of the work-sheets'the clamping device. I is also raised away from the platen ing device whic v top `and A be stationary.

,with the table, and thus be stationary,

to release thc same from engagement with the paper sheets and permit withdrawal thereof. 'lhe said papcr-clamp b Y reason of its extending downward paralle with the side edge of the platen and by reason of its being in close proximity preferably with said edge of the platen will serve as a work-gage, as well as a work-holder, so that there is therein constituted a combined workholder and work-gave.

From the fhregoing it will be observed that my invention includes a combined workholder and work-gage operating in connection with and b the action of a carbon-holdli is capable of being raised to apredetermined height relative to the platen for efectinga separation of the carbon from its contacting work-sheet, and auxiliary or second carbon-carrier constructed ,to operate simultaneously with the first-mentioned carbon-carrier in bein raised away from the platen and effecting a o a separation of the carbon from the work-sheet, together with means for effecting proper cooperation of said work-holder and carbon-holders and means for guiding and limitingr the extent of movement of the operable parts to positionv the same properly to permit said parts to be operated simultaneously or in successive order, as the case may be, and in connection with and coacting with the parts just described the invention includes also means for carrying and feeding the carbon-paper from the rear end of the platen. 4 It is to be understood that the diierent arts of the structure herein described may modified to a considerable extent and yet be lwithin the spirit of my invention. For

instance, means maybe provided on the lever DIL-such, for instance, as a stop or pest N to engage with the table or the under face of the,trackframe B or any other object to prevent the lsaid lever Ns from being elevated beyond a predetermined point, or the-said lever can beconstruotrd to abut against the railof the track-frame after reaching a predeterminedv height, and thus be limited in its vertical movement, or an adjusting-screw N may be threaded into the top of the table in the path of the rear end of the lever N. Furthermore, the means for limiting the movement` of-the clamp l may be of form difiere-nt from the pins i illustrated.

The platen employe in connection with my inventionis preferably of the flat-surface style, and it is to be understood that it may be hinged to the table, as at c, and be tiltable or the same be rigidly secured to the table- It is to be understood also that the track-frame B may or it may be hinged at its rear end, as at l `igs., l4 .and 2, and be tiltable, and it may rest inmornml position upon the upper surface of t the platen and serve as an additional workholder or be constructed of greater length 1430 IOO IXO
